Comment 3 for bug 1974054

I have no manually installed extensions and I also removed the above extensions dir too.

When I launch extension-manager (also cheese FYI) I get:
[3254489.563] wl_display@1.delete_id([3254489.568] wl_display@1.error(nil, 7, "failed to import supplied dmabufs: Arguments are inconsistent (for example, a valid context requires buffers not supplied by a ")
42)
Gdk-Message: 12:22:58.093: Error flushing display: Protocol error

Kindly note that the Brave browser is taking just 0.7%, there is nothing changing on the screen; and also when it happened, I closed all opened apps and CPU usage for gnome-shell was the same.
